University of Pennsylvania Radiocarbon Dates X

Abstract

This date list includes those series of samples completed in this laboratory as of November, 1966. The B.P. ages are based upon A.D. 1950, and are calculated with a half-life value of 5568 yr. All samples were counted at least twice for periods of not less than 1000 min each. Errors quoted are derived from measurements of sample, background, and modern-age calibration, but do not include any half-life error. All samples were pretreated with 3N HCl, and some, where noted, received additional pretreatment with 2% NaOH for the removal of possible humic contaminants.

A Review of Archaeological and Paleoecological Radiocarbon Dating in Bolivia

“…In fact, one of the anthropogenic features that dominates the Central Altiplano landscape are sizeable mounds produced as a consequence of overlapping human occupations (Ponce Sanginés, 1970). Some of the earliest systematic archaeological research conducted in the region, involved excavating and dating some of the mounds such as Wankarani and Sokotiña (Stuckenrath, 1967;Wendt et al, 1962). Horizontal and vertical excavations and dating of Chuquiña, Kella Kellani, Pusno, and San Andrés during the 1990s and 2000s, provided a stronger temporal framework for addressing questions about the economy and social organization of these early communities (Bermann & Estévez Castillo, 1993Fox, 2007;McAndrews, 2005).…”

Plant Husbandry in Early Neolithic Nea Nikomedeia, Greece

“…Three radiocarbon determinations are available for the early Neolithic level: 6230 ± 150 s.c. (Q-655), 5605 ± 90 s.c. (P-1202), 5330 ± 75 B.c. (P-1203) (GODWIN & WILLIS 1962, STUCKENRATH 1967. Comparison with radiocarbon dates for other early Neolithic sites in southeastern Europe and southwestern Asia suggests that the date of 6230 B.C.…”
